REVOLVINGr-SEAT DAVENPORT.

insaeae.

T all whom it may concern:

Be it lrnown that we, WENDELIN P, SENG and Josnr Kxnrcox, citizens of the United States, and residents of the city of Chicago, in the county of Cook and State of lllinois, have invented certain new and useful lmprovements invv Revolving-Seat Davenports; and we dohereby declare that the following is a full, clear, and exact description of the same, reference being hadto the accompany-- ing drawings, and to the numbers of reference marked thereon, which form a part of this specification. Y

rlhis invention has for its object an improvement in the revolving seat sofa bed or davenport for which United States Letters Patent No. $418,305, wasV issued to G. E. Holmes,` A. Gr'. Bostrom. and J. h/LBostrom, on the 26th day of March, 1907. j

` |lhe object ofthe invention is to afford certain improvements in the construction of such devices in respect to the locking mechanism, as will be hereinafter more definitely pointed out and claimed,reference being had to the accompanying drawings, in which-- Figure 1 is a transverse section taken at the end ofthe couch or bed and showing the same in its folded position. Fig. 2 is a similar view showing the same in its open or extended position. Fig 3 is a longitudinal sectional view on the line 3 3 of Fig. 1, showing the couch seat inverted and the parts in position for the opening of the bed. Fig. 4c is an enlarged fragmentary detail of the lock shown in Fig. 3. Fig. 5 is `a fragmentary section on line 5 -5 of Fig d. Fig. 6 is an enlarged detail of the locking mechanism showing the same in locking position. Fig. 7 is a section taken on line 7#7 of Fig. 6. Fig. V8 is an enlarged fragmentary detail and face view showing the locking plate.

As shown in the drawings: the bed cornprises any suitable frame such as are usual for davenports or the like, comprising a per marient back l, and end members 2, which are connected longitudinally at the rear to afford a rigid structure, said end members or arms2, being also connected with the back to afford the requisite strength. Beneath said end members are provided casters 3, and secured on each of the end members is a pivot plate having means thereon for receiving therethrough the flanged'head of the 4pivot pin 7 ,secured in the complemental Specification of Letters Patent.

pivot plate 8, which, as shown, in Figs. 1 and 2, .is secured to the bed frame. Said pivot pin 7, is secured near the inner. end of the pivot plate 8, when adjusted in the couch position, as shown in Fig. 1,' and extending froma point below said pivot pin is a cycloidally curved slot which terminates near the upper edge and oppositeend of said plate, as shown in Fig. 1, and at said upper end of the slot is extended outwardly substantially horizontally affording a shoulder l0, jutting into the slot.

Secured on the pivot plate, in position to engageJ in the slot in the complemental pivot plate 1s a pin l1, as shown cylindric in form and of a diameter approximating the width of the slot and adapted when the bed is folded inwardly and adjusted as shown in Fig. 1, to seat in the opposite portion of the slot above the shoulder 10, to positively hold said portion from turning inwardly because of any weight upon the rear side thereof.

Secured upon the seat 12, which, of course, may be of any desiredV construction, at the front edge thereof is a downwardly projecting plate 50, which coincides with the front of the couch when in the position shown in Fig. 1, and conceals the mechanism and which extends upwardly along the bed is opened, as shown in Fig. 2.

Supported upon the seat Vframe are downwardly directed straps 13, of metal riveted thereto at the inner edge of said frame and on each of which is pivotally engaged a relatively short bed frame section 14E, which extends equally onA opposite sides of said strap 13, and is hingedly connected withA complemental end frame sections 15 and 16, the former of which is pivotally engaged on a link v17 connected therewith and with the seat frame of said couch, as shown in Figs. land 2. rFhe latter of said frame members ateach end of the couch or bed is provided near its extremity with a leg 1S, which is pivoted thereto near its upper end and is of a length to rest upon the floor when the couch is extended horizontally, as shown in Fig. 2. The upper end of said leg extends slightly above said bed frame andV connected therewith and with the pivot pin at the upper end of the strap Ill@ ends of sections 15 which complete the bed frame. And secured to said frame is a spring wirev fabric of any suitable kind or character. Said fabric, being constructed of parallell spring engaged longitudinal ,wires or members, and transverse wires or members Ywhich permit the bed frame to fold' at the pivotal section or at the hinges afforded between the frame members '14, 15, and 16. As shown, said frame members are constructed of structural steel, as, fork instance, angle bars, and the webs and Hanges thereof arev so engage'd'together that when the lframe section 16, is turnedv upwardly at a right angleV with the short pivotally supported section let, the iianges of sections 111 and 16, lock, which causes the section 14, to rotate until. the'fianges on the sections 14 and 15,.mutually engage so that the sections 15 and 16,v lwhen the bed is closed vare parallel and the leg 18, is folded inwardly thereby to the position shown in Fig. 1.

When 'so folded the bed frame or mattress frame affords a receptacle beneath the cushion adapted to contain all the bedding necessaryrwhen thebed is extended. Means are provided for locking the inner edge of the Y seat. VThe upper ends of saidV rods 20 and 40 22, as shown Viii-Fig. 9, are each bent to aordvan outwardly directed arm 23, each vof, which pivotally engages abolt 24, each *of a-length slightly 'greater than half of f 'fthe couch seat or cushion. The inner ends of said .bolts are pivotally connected on a link 25, rigidlysecured on the end-of the locking rod 21, as shown in Fig. 5, so that lthe rotation of said rod 21, in either direc* l. tionjactuates said bolts either to extend or retractl the sameinto engagement with the locking plates'27, seeuredon the couch ends, as shown in Fig. 3, or to retract the same to permit free rotation of the bed. From the construction described, obviously said bolt-s `may be operatedby -utilizing'either of said rods therefor, using lthe upper hooked end thereforV asa erankfor that purpose.

V-']`heoperatio`n is as follows: `With the Y 1 lcouch adjusted as shown in Fig.` 1, inwhich the bedding isV inelosed Within the bed frame,

the. operator" lifts the front edge of the couch, drawing the samevvery slightly outwardly yto release theipinll, from the shouli der 10,7in the curved slot in the pivot plates and inverts thecouch. In this position the locking `bolts before described are disposed along the rear edge of the bed frame and may be released by engaging either of the same and swinging the bolts to the position shown in Fig. 3, in which position the bolts are shot into the apertures in the straps 27,

.on the end frames of the couch, thus rigidly y holding the inner end of the bed frame in adjusted position. rihe operator new reaches over and engages the inner edge of the outer folding section of the bed frame or that corresponding with the end members i6, of the bed frame and swings the same Vover to the position shown in Fig. 2, such movement acting to lift the tilting` section to horizontal position and elevating the inner edge of the bed frame upon the pivotally engaged links 17, thus elevating the bed as a whole to a horizontal position and affording a continuous supporting spring surface without intermediate bars or rails.

The outer swing of the outer bed section serves to swing the legs 18, downwardly to supporting position, as shown in Fig. 2, inasmuch as the radial distance between the pivotal connection of the leg on the end frame member 16, and the inner pivotal connection of the link 19, is materially increased. In this position the bed is firmly supported and securely locked from movement. lhen it is desired to close the same the outer edge of the outer folding section of the bed frame is lifted and turned over upon the inner frame section. This movement necessitates the tilting of the short intermediate section 14, when the end frame Vmembers 16,' are at a right angle with said intermediate frame members and these in turn when at a right angle with the inner frame members, 15, are limited from further movement relative thereto. ln consequence, all the bedding is inclosed in the receptacle thus formed and when the outer section is turned inwardly parallel the inner, the hooks at the upper ends of the locking rods 20, 21 and 22, are turned inwardly over the same, thus retracting the bolts and leaving the bed free to turn to its normal position as a couch, as shown in Fig. 1, and in this position, as before described, the offset or shoulder 10, projecting into the slot serves as a positive lock to maintain the couch in operative position.

Of course, detailsof the construction may be varied, as, for instance, other means may be provided for locking the sections of the bed Vframe in closed position and when released therefrom looking the open bed in its extended position. We have, however, shown butV a preferred form of our invention and we therefore do not purpose limiting ourselves otherwise than necessitated by the prior art.

Vile claim as our invention:

1. In a device of the class described, the

combination With a back and side members, of a seat pivotally connected to the side members, a folding bed-frame section pivoted to said seat, oppositely movable locking bolts secured to said seat, a link pivotally connecting the inner ends of said locking bolts, a rod rigidly secured to said link for operating the latter to project or retract said bolts with respect to said side members respectively, and rods connected to said lock ing bolts and having angled ends adapted to engage and bind together the sections of the bed-frame when folded, said rods being adapted to shift said bolts to looking or retracted position, and said side members and looking bolts being formed and arranged for mutual engagement When said bolts are projected for looking the seat.

2. A device of the class described comprising a stationary frame having side members, a seat pivotally connected to said side members, and a folding` bed bottom carried on the reverse side of said seat, in combination With a locking bolt secured4 to said seat and movable outwardly to engage one of said side members, and a plurality of spaced rods disposed transversely of said seat and connected turnably to said locking bolt and having shouldered ends adapted to engage and lock together the sections of the bed bottom when folded, said rods being formed and adapted for shifting said bolt to locking or retracted position in releasing and locking the bed bottom respectively.

In testimony whereof We have hereunto subscribed our names in the presence of tWo subscribing Witnesses.
